感知无线电有关的仿真，希望对大家有用(Simulation-related cognitive radio, in the hope that useful to everybody)

我的这个源码可以直接绘制一个正圆。方便又实惠哦(mine is good,it can print a circle)

说明：  使用DFT做频率估计的matlab仿真编程程序(Frequency Estimation Using DFT)

kohonen网络的聚类算法—网络入侵聚类，数学建模常用模型(clustering algorithm kohonen network- network intrusion clustering, mathematical modeling commonly used model)

在线快速傅里叶变换（FFT）分析演示，Matlab/Similink(Online fast Fourier transform (FFT) analysis of demonstration, Matlab/Similink)

matlab ssim 代码 可以跑的，其所作的特征提取比sift要好，而且计算简单(can run the Matlab ssim code, made the feature extraction is better than sift, and simple)

说明：  从电脑中选择一个图片，本程序可对图片完成类型转换，几何运算，代数运算（平均法降噪和减数运算），傅里叶变换，图像增强（包括灰度值变换，直方图均衡化，邻域平均法和中值滤波波法），图像复原，图像分割等功能。(Choose a picture from the computer, this program can complete type conversion, geometric operation, algebraic operation (average noise reduction and reduction), Fourier transform, image enhancement (including gray value transformation, histogram equalization, neighborhood averaging and median filtering wave method), image restoration, image segmentation and other functions.)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)
